The main object of this invention is to provide a heating stove with an improved construction of sheet metal heating drum. Objects pertaining to details and econo- 5 mies of construction and operation will defi nitely appear from the description. to follow. A stove embodying a preferred form of my invention is clearly illustrated in the accompanying drawing, in which: 1O

Fig. 3 is a horizontal sectional view taken on the broken line 3-3 of Fig. 2.

The parts will be identified by their numerheating drum with inturned bottom flange 4'1 and with straight top which surrounds the combustion chamber 3 forminga broad circulating passage for the products of c0m-= bustion in order to insure thorough heat 'delivery therefrom.' Inturned flange 41 rests ring 5 projects to finishthe bottom of the rapreferably nickel-plated.= V

The'clean-out door 7 is provided at this point through saidrextem sion. It Will benoted that there is arpasis provided with a smoke pipe collar 9. This. plate. is either boltedvor spot weldedto the fianged walls of the combustion, chamber and 'theradiating drum.

Thestove, when operated to its reasonable capacity, is very economical of fuel because of the opportunity 'ofcomplete heat transfer due tothe fullexpansion and circulation in 'a comparatively thin layer of the entire products of combustion without the me,

cessity of any direct flue and consequently without the, occasion of any losses thereby.
